What is the Process of Boat Propeller Repair

How are boat propellers repaired? Are inboard and outboard propellers repaired the same way? Walk into our propeller repair shop… Inboard and outboard boat propeller repairs are similar in some ways and different in others. Depending on the size and material of a propeller there are different steps that may be taken. When we receive your damaged boat propeller at our customer service desk it is tagged with your name and any special instructions for the repair technicians. Your propeller is assigned a control number to assure that we repair and return the propeller you gave us. Outboard propellers are

Stainless Steel vs Aluminum Outboards

Material choices for outboard and sterndrive propellers are Aluminum and Stainless. How does an aluminum propeller differ from a stainless steel propeller? Aluminum Propeller Aluminum boat propellers are relatively inexpensive, easy to repair, and under normal conditions can last for many years. They’re great for small and mid-sized boats. Aluminum boat propellers are lightweight at about 1/3 the weight of stainless and will flex to help prevent damage to your outboard motor if it strikes something. Aluminum boat props are available for nearly any outboard or sterndrive motor you may have. Leisurely boaters will be well suited with an aluminum

THANK YOU Giving Back Local

2020 has been an economically difficult year for many, and Tacoma Propeller wants our customers to know how much we appreciate you for choosing us for your prop and shafting needs. Our 6-person staff is deeply thankful. We are happy to have been here this year as an essential business to help both our government accounts and our pleasure-boating customers. Our November monthly promotion was a promise to pay back to our local community. A percentage of each inboard sold during November has become non-perishable groceries which have been donated to feed253. feed253 is a local non-profit that has been

Should I have a 3 or 4 Blade Outboard Propeller?

Should I have a 3 or 4 Blade Outboard Propeller? Or even 5? We regularly help customers who call or come in asking for a outboard boat propeller with more blades because they want to go faster. Unfortunately, that’s just not how outboard boat propellers work. Here, we’ll walk through the applications for different outboard / sterndrive boat propellers based on number of propeller blades, and outline some considerations to make when switching from one to another. Best conditions to run 3B: We recommend 3-blade boat propellers for most recreational boats with 3, 4, and 6 cylinder outboards and I/0

July is National Ice Cream Month

It’s here again! Hot, sweaty, summer sun, and the perfect season for our favorite treat!  July is National Ice Cream Month. In 1984, Senator Walter Dee Huddleston of Kentucky introduced a resolution to proclaim the month of July 1984 National Ice Cream Month and the 15th of the month National Ice Cream Day. The bill was signed into law that year by Ronald Reagan, making ice cream the official treat of July nationwide! Even though the bill only specified that July 1984 was National Ice Cream Month, the tradition carries on—to our tasty delight. Here in Washington, we have created

What Causes Ventilation?

What is Ventilation? Ventilation is often confused with cavitation. For information about cavitation, see our What is Cavitation post. Ventilation is when surface air or exhaust gasses are drawn into the propeller blades. When this occurs, boat speed is lost and engine RPM increases rapidly. What causes Ventilation? Ventilation can result from: excessively tight cornering a motor that is mounted very high on the transom over trimming the outboard motor or sterndrive concave hull damage causing the transom to lift and pulling the propeller toward the water’s surface Can ventilation ever work to your advantage? Occasionally, venting a propeller can

What is the difference between Bronze and Nibral?

What is NiBrAl? And how is it different from bronze? In the realm of inboard propellers and ski wheels, we primarily see products made of Manganese Bronze VS NiBrAl which is an alloy blend with nickel, bronze, and aluminum. While the two look very much alike, nibral is considered harder, stronger and more corrosion resistant. To get technical, Manganese Bronze Alloy has a tensile strength of 65,000 PSI, and yield strength of 25,000 PSI. Nibral has a tensile strength of 90,000 PSI, and a yield strength of 37,000. In accordance with those features, nibral does generally cost more and take

What is Cavitation?

What is Cavitation? Cavitation is bubbles caused by excessive propeller speed or loading. The water vaporizes or boils due to the extreme reduction of pressure on the back of the propeller blade. Many propellers partially cavitate during normal operation, but excessive cavitation can result in physical damage to the propeller’s blade surface due to the collapse of microscopic bubbles on the blade. Cavitation can cause: pitting on the surface of propeller blades vibrations when running – just like having an unbalanced or pitch-damaged prop reduced bite reduced overall efficiency What can be done to prevent cavitation or fix the damage

All about Anodes and Electrolytic Corrosion

How do anodes protect my boat from electrolytic corrosion? What are sacrificial anodes and why do I need to replace them? Any time you have exposed metals on your boat, you’ll want to protect them with sacrificial anodes. Anodes are often referred to as “zincs,” although different materials are used in different applications. Anodes are alloys intended to take the damage caused by electrolysis in the water before the metals on your boat are damaged. Electrolysis in water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. This can be caused
